Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
- Support the ADL5240 variable gain amplifier (VGA).
- Support the ADA4961 digital gain amplifier (DGA).
* dps310
- New driver, in several parts from different authors for this temp
and pressure sensor.
- Includes errata workaround for a temperature reading issue.
* stk3310
- Support the stk3335, mostly ID.
Features and cleanups
* core
- drop error handling on debugfs registration.
- harden by making sure we don't overrun iio_chan_info_postfix.
* docs
- convert remaining docs to rst. At somepoint we'll fit these few
into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.
* ad_sigma_delta
- Drop a pointless goto.
* ad2s1210
- Drop pointless platform data null check seeing as we don't actually
use platform data anymore.
* ad7124
- Relax limitation on channel numbers to allow pseudo different channels.
- Support control of whether the input is buffered via DT.
- Use dynamic allocation for channel configuration to make it easier
to support new devices.
- YAML binding conversion.
* ad7150
- Comment tidy up.
- Consistent and simple if (ret) handling of i2c errors.
- FIELD_GET and GENMASK.
- Ternary rather than !!(condition) for readability.
- Use macros to avoid repetition of channel definitions.
* ad7606
- Add software channel config (rather that pin controlled)
- Refactor to simplify addition of new part in future.
* ad7746
- of_deivce_id table.
* ad7780
- MAINTAINERS entry
- YAML DT bindings.
* ad8366
- Stop using core mlock in favour of well scoped local lock.
- SPDX + copyright date update.
* ad9834
- of_device_id table
* adf4371
- Add support for output stage muting before lock on has occured.
* adis library
- MAINTAINERS entry to reflect that this now Alexandru's problem ;)
* adis162xx:
- Fix a slightly incorrect set of comments and print statements on
minimum supported voltage.
* adis16203
- of_device_id table.
* adis16240
- Add of_device_id table (in two parts as first patch only used it for
MODULE_DEVICE_TABLE.)
* adt7316-spi
- of_device_id table
* adxl372
- YAML DT binding conversion.
- Cleanup use of buffer callback functions (precursor to core rework).
* bh1710
- Simplify getting the i2c adapter from the client.
* dht11
- Mote to newer GPIO consumer interface.
* kxcjk-1013.c
- Add binding for sensor in display of some ultrabooks after userspace
tools updated for it not be a problem to report two similar sensors.
* imx7d
- drop unused variables.
- white space
- define instead of variable for clock frequency that is fixed.
- drop pointless error message.
* messon_saradc
- SPDX
* sps30
- MAINTAINERS entry
- YAML binding conversion.
* st_accel
- Tidy up ordering in various buffer related callbacks. This is
part of a long running effort to simplify the core code.
* stm32-dfsdm:
- Manage the resolution cleanly in triggerd modes.
- Add fast mode support which allows more flexible filter choices.
- Add a comment on the reason for a 16 bit record when technically
not 'required'.
* st_lsm6dsx
- Embed device name in the sensor_settings struct as i3c doesn't
have a convenient name field to use for this.
* xilinx-adc
- Relax constraints on supported platforms to reflect that this
can used with FPGAs on PCIe cards and hence many architectures.
* counters/ftm-quaddec
- Fix some formatting io MODULE_AUTHOR
- MAINTAINERS entry
Fixes
* tools
- fix incorrect handling of 32 bit channels.
* sca3000
- Potential endian bug that is unlikely to bite anyone (be64 host
seems unlikely for this old part).
* stm32-adc
- Add vdda-supply. On some boards it needs to be turned on to supply
the ADC. DT bindings included.
* stm32-dfsdm
- Fix output resolution to work with filter orders other than 3.
- Fix output datatype as it's signed and previously claimed not to be.

of a spinlock between the hardirq and the thread.
Tools
* event-monitor
- report unsupported events. We keep expanding what can come from drivers
so give a helpful error if one turns up in an out of date userspace
program.

This is the bulk of GPIO changes for the v4.3 kernel cycle:
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc
versions of the descriptor calls that did not use the flags
argument on the end. This was around for too long and eventually
Uwe Kleine-König took the time to clean it out and the last
users are removed along with the macros in this tag. In several
cases the use of flags simplifies the code. For this reason we
have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
up until we hammer in the nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff
we have i the kernel to discourage people from reinventing
a square wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO
IRQ chip instead of using one class for all chips, as the current
code will not work with systems with several GPIO chips doing
lockdep debugging.
- Protect against driver unloading also when a GPIO line is only
used as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent
device driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO
drivers. This was an ARM specific function that is replaced
with the generic irq_modify_status() where special flags
are actually needed.
- When an OF node has a pin range for its GPIOs, return
-EPROBE_DEFER if the pin controller isn't available.
Pretty logical, yet needed to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own
irq_*_resources call back, then call these instead of the
defaults provided by the GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not
properly documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the
generic GPIO driver.
- Clean out platform data support from the Emma Mobile (EM)
driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

Merge tag 'gpio-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.3 kernel cycle.
There is quite a lot going on in the GPIO subsystem this merge window,
so the main matter is decribed below.
The hits in other subsystems when making the GPIO flags optional are
all ACKed by their respective subsystem maintainers.
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
of the descriptor calls that did not use the flags argument on the
end. This was around for too long and eventually Uwe Kleine-König
took the time to clean it out and the last users are removed along
with the macros in this tag. In several cases the use of flags
simplifies the code. For this reason we have (ACKed) patches
hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff we
have i the kernel to discourage people from reinventing a square
wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO IRQ
chip instead of using one class for all chips, as the current code
will not work with systems with several GPIO chips doing lockdep
debugging.
- Protect against driver unloading also when a GPIO line is only used
as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent device
driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data().
This series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO drivers.
This was an ARM specific function that is replaced with the generic
irq_modify_status() where special flags are actually needed.
- When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
if the pin controller isn't available. Pretty logical, yet needed
to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
back, then call these instead of the defaults provided by the
GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not properly
documented.
Driver improvements:

Second set of new device support, features and cleanup for the 4.3 cycle.
Take 2 also includes a fix set that was too late for the 4.2 cycle.
As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.
Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
stopped the tool working.

* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
common support to allow different WHOAMI register addresses, devices with
fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)

Driver cleanup / fixes
* mxs-lradc
- Clarify which parts are supported.
- Fix spelling erorrs.
- Missing/extra includes
- reorder includes
- add datasheet name listings for all usable channels (to allow them
to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
electrical characteristics (defining a minimum sample time)
* dht11
- whitespace
- additional docs
- avoid mulitple assignments in one line
- Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
- expand area locked by a mutex to cover all the use of the
data->buffer.
- use descriptive naming for a mask instead of a magic value.
* berin2-adc
- pass up an error code rather that a generic error
- constify the iio_chan_spec
- some other little tidy ups.
* stk8312
- fix a dependency on triggered buffers in kconfig
- add a check for invalid attribute values
- improve error handling by returning error codes where possible and
return immediately where relevant
- rework macro defs to use GENMASK etc
- change some variable types to reduce unnecessary casting
- clean up code style
- drop a local buffer copy for bulk reads and use the one in data->buffer
instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
verifying the expected part was there. This was in response to a wrong
ACPI entry on the WinBook TW100.
* mma8452
- fix _get_hp_filter_index
- drop a double include
- pass up an error code rather than rewriting it
- range check input values to attribute writes
- register defs tidy up using GENMASK and reordering them to be easier to
follow.
- various coding style cleanups
- put the Kconfig entry in the write place (alphabetically).
Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
usage of the tools core code. Also convert a double pointer to a single
one as the extra level of indirection was unnecessary.
Docs
* DocBook introduction by Daniel Baluta. Glad we are beginning to
draw together some more introductory docs to suplement the various
tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.

iio: Export I2C module alias information in missing drivers
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.
